Dual Gauge Theory for Two Dimensional Superfluid Turbulence
Tobias Helbig, Sayak Bhattacharjee, Srinivas Raghu
We describe turbulent hydrodynamics of superfluids in two spatial dimensions via the dynamics of point-like vortices coupled to an emergent 2+1 dimensional gauge field. The…
A Systematic Search for Big Dippers in ASAS-SN
B. JoHantgen, D. M. Rowan, R. Forés-Toribio +6
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplan…
Supernova Rates and Luminosity Functions from ASAS-SN III: Over a Decade of Type Ia SNe and Their Subtypes
Dhvanil D. Desai, Benjamin J. Shappee, Christopher S. Kochanek +11
We present volumetric rates and luminosity functions (LFs) of Type Ia supernovae (SNe Ia) from the All-Sky Automated Survey for Supernovae (ASAS-SN), covering the 11-year period fr…
The Most Energetic Transients: Tidal Disruptions of High-Mass Stars
Jason T. Hinkle, Benjamin J. Shappee, Katie Auchettl +13
We present the class of extreme nuclear transients (ENTs), including the most energetic single transient yet discovered, Gaia18cdj. Each ENT is coincident with its host-galaxy nucl…
The Unhurried Universe: A Continued Search for Long Term Variability in ASAS-SN
Sydney Petz, C. S. Kochanek, K. Z. Stanek +4
We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larg…
Supernova rates and luminosity functions from ASAS-SN II: 2014-2017 core-collapse supernovae and their subtypes
T. Pessi, D. D. Desai, J. L. Prieto +7
The volumetric rates and luminosity functions (LFs) of core-collapse supernovae (ccSN) and their subtypes are important for understanding the cosmic history of star formation and t…
